hard disk install confused by two iso images

[H.S.]

I installed F7 earlier today using installation from hard disk method. I 
had downloaded the DVD torrent to /dev/hda4 in /path/to/dir/Fedora-7-i386.

When I started the installation process, F7 detected my disks as sda and 
sdb (instead of hda and hdb). Upon choosing the install from hard disk 
option, choosing /dev/sda4, and giving the path to the directory 
/path/to/dir/Fedora-7-i386 (which contained two iso images: 
F-7-i386-rescuecd.iso and F-7-i386-DVD.iso), the installer threw an 
exception. It turned out that if I put the DVD iso in its own directory, 
then the install went fine. I ended up have the iso in /dev/sda4/f7 
(directory was f7). It appears that the two ISO images in the same 
directory confused the installer.
